Hi Bernd, I can confirm, that NWA 4808 and 4473 are paired (were classified at the same place). We didn't know, how to act correctly, as the owner of 4473, insisted in spring, that he wished, that we never should mention paired material in his possession or his name in our Ads. Like he seems to do too, when he has material for sale paired with ours, if I look here and there into ebay. NWA 4808 isn't listed in the Bulletin yet, therefore that little dilemma.
Anyway it is fascinating material. Additionally to the observations you made, this meteorite has some more unusual aspects. So no eucritic components were found in those stones, but fragments of three different diogenitic precursors. Therefore it must have a somewhat unusual impact history. Our "special" was sold out the same day, we found a few more slices in our stock, now only 3 or 4 small ones are left. As small as NWA 4808 was, it was quite heterogeneous, macroscopically the slices were quite different from each other. If someone is looking for larger surfaces, I saw Mike Cottingham having NWA 4473 on ebay some weeks ago, perhaps he has some left. Am I the only one, who can't await, that Dawn will arrive at Vesta?

The only difference is that the crystal faces of the orthopyroxene mineral clasts in NWA 4473 are less well developed (in my piece!). In oher words, most pyroxene cystals in my NWA 4473 piece are anhedral and a few are subhedral.
